Polyethyleneterephthalate (PET) is a linear thermoplastics comprising of repeating ethylene glycol and terephthalic acid chains. It is transparent, resistive mechanically and lightweight. The main area of the use is production of packages.
PET has become especially popular in recent years because it is exceptionally:
- Resistant to breakage
- Easily transformable and colourable
PET is a very inert material. It is resistant to effect of microorganisms and non-reactive with food products and, therefore, it is very suitable for food, drink and pharmaceuticals packages. Health care institutions worldwide approved PET as suitable for food and beverages industries.
